If you want to relax by listening to diagrammatic, Predragian
vision of field theory, I will cover the material in chapters 2-3 of
Field Theory
in n lectures, n unknown.
The exposition assumes no prior knowledge of anything (other
than Taylor expansion of an exponential, taking derivatives,
and inate knack for doodling).
The techniques covered apply to QFT, Stat Mech and stochastic processes.

Goals:
We work through the 1-loop renormalization for the phi^3 scalar field theory,
in order to verify to the lowest order the general renormalization theory
developed in the last part of the course. We also learn how to use dimensional
regularization in order to evaluate explicitely the divergent integrals.

Solution:
a very nice set of 2002-2003 lecture notes on phi^3 field theory by
Mark Srednicki, UC Santa Barbara.
The exam consisted in checking Chapters 13, 14 and 16 of Srednicki lecture notes. Everybody aced it, but that does not mean an A in the
course for the problem sets laggards.

Moral lesson:
Today even crackpots use LaTeX, and everything looks like a god given truth. As a physicist you should not believe
anything that you cannot check, especially if your work depends on it. I gave you a wrong
formula for the
surface of a sphere
(it gives S_2 = 1/(2 \pi), for example), and nobody checked whether if made sense for cases you know.
My suggestion to use Schwinger rep rather than Feynman rep was not helpful either.

Appologies

Starting fall I will go through the entire
classical and quantum chaos webbook in 2 semesters - this too will turn out to be
a form of field theory, not any less beautiful than what we learned this semester. Hope you rejoin me.
